In order to collect the ransom offered by the family of a kidnapped industrialist, a terminally-ill man frames himself for the crime, but he accidentally uncovers the real culprit.

A dying man frames himself for the kidnapping and murder of an industrialist so his wife and daughter can benefit from the reward money. However, his plan goes awry when he is cured!—Marty McKee <[email protected]>

Diagnosed as having a fatal brain tumor, insurance investigator Paul Cameron (George Kennedy) provides for his family by confessing to the murder of a wealthy industrialist. Carefully constructing a case for his prosecution, he negotiates under a pseudonym for the sizable reward offered by the victim's associates. Despite the defense of attorney Mario Gambretti (Eli Wallach), Cameron is convicted. After collapsing while leaving the courtroom Cameron is subjected to successful laser beam surgery. Fully recovered, Cameron faces imprisonment for a crime which he did not commit. Informed by Gambretti that a new trial is impossible without further evidence, Cameron escapes from the hospital and stalks the real killer.
